Answer:

Step-by-step explanation:

3x2x2=12
5x7x3=105

The midpoint is (0.5, 1.5)
you use (x2-x1)/2 and you add that number to x1 got x midpoint
and is the same way to find y
The value of x is 84 degrees
Answer:
The answer to your question is the big dog weighs 120 pounds
Step-by-step explanation:
Data
big dog = b
medium dog = m
small dog = s
Equations
b = 5s
m = 12 + s
s = 2/3 m
Process
1.- Substitute m in the last equation
s = 2/3(12 + s)
s = 24/3 + 2/3s
s - 2/3s = 8
1/3 s = 8
s = 8(3)
s = 24 pounds
2.- Substitute s in the first equation
b = 5(24)
b = 120 pounds
The correct answer is B)
Hope this helps!
